Worked Solution & Example Answer:Copy the structure of the aspirin molecule shown into your answer book - Leaving Cert Chemistry - Question g - 2015
Step 1
Draw a circle around the carboxylic acid group.
Answer
To indicate the carboxylic acid group within the aspirin molecule, draw a circle around the part of the structure that contains the following elements:
- The carbon atom (C) connected to a hydroxyl group (–OH).
- The carbon atom (C) part of the carbonyl (C=O) group.
- This should include the –COOH functional group as part of the circle.
Step 2
Draw a rectangle around the carbonyl part of the ester group.
Answer
To highlight the carbonyl part of the ester group, draw a rectangle around the carbon atom that is double-bonded to an oxygen atom (C=O) in the ester part of the aspirin molecule. This part is typically adjacent to the aromatic ring and should be clearly marked to show that it is the carbonyl component of the ester functional group.
